Costs, productivity and reservoir studies
This service, a collaboration between EssencePS and Dinova Petroleum, provides a major improvement in business workflows and management of reservoirs, resulting in optimised performance, reduced costs and mitigated risks.
Subscription service
Instead of one-off reservoir studies, which are irregular and can take months to negotiate and complete, the Evergreen service is subscription based, and for an annual fee the history match and production uncertainty is regularly updated and available, so that decisions can be made in a timely manner based on up to date information.
Evergreen fields
Traditional reservoir studies are carried out as discrete studies, with limited continuity of engineers, data or knowledge. With modern tools, engineers can now perform history matching or uncertainty studies in days. This allows the reservoir studies to be performed as a continuous process, with the models and uncertainties updated each time new information is obtained.
We propose a service which facilitates this continual process, with a commitment over a period of time and continual updating of models and conclusions.
Timely intervention
With a continuous process, rapid revisions of forecasts are possible, and timely intervention becomes a reality. This keeps the decision makers, geomodellers and reservoir engineers in step, and the decision makers always have available up to date reservoir analysis.
Investment decisions
An evergreen model allows rapid decisions on investments or divestments, taking into account changes in economic conditions or approaches from competitors.
Unexpected events
Whenever there is an unexpected event in the field:
- water breakthrough
- GOR increase
- Well Shut down or lost
- compressor shut down
- pump failure (producer or injector)
The production engineer is left to make his own decisions on how to react, without much knowledge of the consequences. With an evergreen model, the reservoir engineer can provide optimized recommendations on the best way forward, or until the breakdown is repaired.
Value of information
In many companies there is no standard protocol for managing information from reservoir studies. Where an individual engineer moves job or project, the knowledge and data can become lost
We propose to manage the necessary information so that access to the official models is always available.
Reduced costs
The Evergreen service can provide an ensemble of uncertainty cases at any time, and is particularly useful for auditors and stake holders, avoiding the need for expensive studies.
It also reduces time spent preparing budgets, and helps decision makers to balance risks and rewards in a more comprehensive way.
Increased production
Rapid decision can be made on:
- reallocation of gas-lift
- changes of pump rates (VSD)
- shutting down high GOR or water producers.
The production engineer can be proactive and propose actions that can increase production. As an example, it can help finding production bottlenecks, and more particularly see the impact on long term production.
